IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 1 58,831, dated January 19, 1875; application filed November 25, 1874.

To all whom it may concern:

Be it known that I, JOHN G. CHASE, of Butland, in the county of Meigs and State of Ohio, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the aocompanyingdrawin gs, which form part of this specification.

My invention relates to an improvement in washing-machines, and is intendedas an improvement upon the patent granted to me July 23, 1872, No. 129,714; and consists in, first, the arrangement and combination of devices by which the smaller rollers are held in contact with the larger one; second, the devices by which the washer is fastened to the tub, all of which will be described more fully hereafter.

The accompanying drawing represents my invention.

a b 0 represent three grooved or corrugated rollers, as described hereafter, of which the roller 0: is the largest and central one, the others measuring about one-half each the diameter of the former, with their axes at an angle of about ninety degrees to that of the roller a, and sufficiently above it as just to bring their surfaces in contact with the large roller. The arrangement of the rollers a b 0 leaves the open space g at the topof the roller a, which space. is of great convenience to the operator for soaping the clothes. The grooves or corrugations in the rollers terminate within a short distance of the ends of the rollers, leaving smooth friction spaces or rings'a, the use of which is to prevent the interlocking of the grooves or corrugations, and consequent rattling of the rollers, when running without fabric between them. The arms f, projecting from the end plates, are on a line with the axis of the large roller, and rest in notches upon the sides of the wash tub, where they are held in position by a Y-sh aped stirrup or loop, 3 the two upper ends of which pass upward between the arms f, and, extending outward over them, bear upon them. The two upper ends of the stirrup are connected and braced across by a rod or bar, '0 their points of connection resting upon the arms f. The

lower end, m, of the stirrup forms a stem, and is provided with a nut, 02, and passes through and under a slot, h, in a projecting lug, l, which lug isfastened to a plate, V, on the outside of the tub. The stirrups may be adjusted by the nut and screw so as to bind the tub and washer rigidly together, or entirely released, when it is desired to remove the washer, by drawing the rod out of the open slot h. The rollers 11 0, as already stated, are also journaled in the end plates, P P, but rest in slots 1', on radial lines of an angle of ninety degrees to the center of the large roller, a. On the ends S of the journals of the smaller rollers, b c, which extend somewhat beyond the end plates, are necks, formed for the purpose of attaching lugs 10. These lugs have on their other ends a button or knob, K, over which passes an elastic band, 0, to a similar button, K, fastened to the end plate, so that the rollers b c are drawn downward by the bands-and held in the slots 1", in'which they are journaled.

The elasticity of the bands by which the rollers are held allows them, whenever the nature of the clothes to be washed requires it,

to yield to the pressure and automatically resume their former positions.

One set of rollers is sufficient for an ordinary washing, and the idle-roller may then be used for a Wringer; but if large pieces are to be washed, both sets will be required.

Having thus described my invention, I claim- 1. In a washing-machine, the combination of rollers a b 0, end plates 1? P, the lugs 19, and buttons K K, with elastic bands 0, substantially as set forth.

2. The stirrup y, brace i, and nut n, in combination with the lug l and projecting armsf, substantially as described.

3. Therollers a b c, with corrugations extending near to their ends, and terminating in the smooth friction-rings a, substantially as set forth and described.

In testimony that I claim the foregoing I have hereunto set my hand.
